Probably your MMR went up a lot but since your rank is still the same you're getting matched with lower MMR players then yourself so you gain less cuz of that.
This is incorrect. You're matched based on MMR, not based on your rank. So, for example, if you are Silver 1 and you queue dodge every time you get to your promos, you'll eventually be playing with Gold 1 or 2 players even though you're Silver 1. When your MMR gets higher than Gold 1 MMR, you'll end up skipping promos and jumping straight into Gold 4.
